4 Claims.

This invention relates to improvements in the construction and erection of fireproof partitions and more particularly to such partitions for use in ships in forming state rooms where weight is an essential element.

Heretofore the state rooms in ships, particularly in large passenger carrying ships, have been formed either of thin metal or laminated wood with wooden stiles and moulding dividing the rooms from each other and forming the corridors or passages between state rooms. Partitions of such character are inflammable as the thin metal melts and the wood burns. It is an object of this invention to construct partitions for this purpose or" an accepted compressed fireproof-ing cut to fit and finished at the factory and provide means for quickly erecting and securing the partitions in the ships which will weigh approximately the same or less than the Wooden or thin metal partitions, so as not to increase the weight of the ship and, at the same time, lessen the work in completing the ship. With hundreds of state rooms in a ship only light weight material, such as thin metal or wood, has been found practicable in such constructions, as the parts are cut and fitted on the ship and then each finished and decorated, consuming considerable time and requiring the employment of many men of various trades.

With these and other objects in View, reference is made to the accompanying sheets of drawings which illustrate an embodiment of this invention as applied to ships, with the understanding that minor detail changes may be made and the partitions used in buildings or for other purposes, without departing from the scope of this invention.

Figure 10 is a view similarto Figure l illustrating another form of this invention employing shaped metal stiles and rails with mouldings.

Figure 11 is a view similar to Figure 2, illus- Figure 16 is a view in transverse central vertical section of Figure 15.

In carrying out this invention, the form illustrated in Figures 1 to 9, inclusive, is preferably built up of a number of sections or panelsof compressed fireproofing, such as the compressed asbestos boards of commerce, vertically stifiened on one side by metallic members and held top and bottom by rigid metal members fastened to the ship or building structure, with the vertical stiffening members preferably covered by metallic pilasters and the top and both holding members covered by metallic cornices and bases, respectively.

In the embodiment as illustrated in Figuresl to 9, inclusive, the partition is made up of a series of vertical sections or panels 1 of commercial compressed fireproofing material in board form, such as asbestos boards which are sold in stock sizes approximately three feet six inches in width and of any desired length. When the dimensions of the partition or wall are known such boards may be cut the proper iength at the factory and the desired reinforcing member secured thereto to provide the desirable rigidity to the partition and to cooperate with the means of securing the meeting edges to each other.

It is preferable to providereinforcing members adjacent each vertical edge of each panel 1, preferably in the form of commercial channel irons 2 having the flanges thereof turned toward the vertical center line of the panel and the flange 3 contacting the surface of the panel secured thereto, preferably as shown in Figures 3 and 5, by extending the flange 3 at the top and bottom to be bent back upon itself to embrace the horizontal edge of the panel and be secured thereto by a screw-threaded tap bolt 4 and by striking out of said flange a plurality of tongues 5 intermediate the ends adapted to be passed through apertures provided therefor in the panel and then bent back upon themselves to firmly hold the body of the panel and flange 3 together. It is preferable to recess the body of the panel, so that the exterior surfaces of the embracing ends of the flanges 3 and tongues 5 lie flush with the outer surfaces of the panel 1 which they engage. It is also preferable to provide a reinforcing or stiffening member along the vertical center line of each panel 1, preferably in the form of commercial channel irons 6, having each oppositely disposed flange provided with a right angular outwardly extending portion '1 adapted to engage the surface of the panel 1 and be secured ..to the panel by extending the flanges 7 about each horizontal end and providing the flange 7 with struck out tongues similar to the tongues 5 to embrace the body of the panel in the same manner as the strengthening members adjacent the meeting edges.

In order to secure the panels in position a metal sill is provided to be secured to the floor and ceiling or deck, as the case may be, which is preferably formed of sheet metal, as shown in section in Figure 2, bent to provide a long vertical side 8, a spaced apart shoulder side 9, a right angular horizontal chair 10 and a depending leg 11 adapted to be held spaced apart from the side 8 by a channel 12 having its flanges spot welded thereto, if desired, so that the ends of the side 8, leg 11 and channel 12 may be secured to the deck by a screw-threaded tap bolt 13 passed through the chair 10 to be engaged in the finished floor or deck. It is preferable to cover the heads of the tap bolts 13 by a channel 14 with its flanges resting upon the chair 10 with one flange in engagement with the side 9. The panels 1 are cut of such length that the bottom may be rested upon the channel 14 of the chair 10 upon the floor or deck with the lower surface in engagement with the part 9 of the lower sill and secured thereto by extending the tap bolts 4 of the lower reinforcing or stiffening members through screwthreaded openings in the sides 9 provided therefor either at the factory or on the job, and the upper ends of the panels likewise engaged to the corresponding member 9 of the upper sill. The

outstanding portions of the reinforcing or stiffening channels 2 and 6 are cut away from the flanges 3 and '7 so as to terminate in line with the end of the longer side 8 of each sill and each sill is completed on that side by a cover formed of sheet metal bent to form a long side 15 of the same length as the side 8 of the sill and engage the short side 11 on the sill and flange of the channel 14 upon the chair l0 and provided with a spaced apart shorter side 16 adapted to engage the end parts of the panel 1, as shown in Figure 2. The cover is preferably held in place by a plurality of screw-threaded tap bolts 17 passing through cover threaded apertures provided therefor, either at the factory or on the job, in the longer side 15 of the cover, the flanges of the channel 14 and the shorter side 9 of the sill.

The bottom of the bottom sill is preferably covered by a conventional base board 18 preferably of rubber composition resting upon the floor or deck and cemented thereto while the upper sill is preferably joined to the ceiling by a sheet metal cornice 19 formed in any design desirable, prefrably with internal edges adapted to contact the outer surface of the sills and ceiling and be secured thereto by screw-threaded tap bolts passing through the cornice body and preferably through the internal edges as well.

In ships the ceiling is usually connected to the underside of the beams of the deck above, as shown in Figure 2. In this case, the ceiling 20 is formed of commercial fireproofing board, and may or may not have a metal facing, as desired. I is preferable to insert a blocking 21 between the underside of the beams 22 and the ceiling boards or panels 20' and engage their abutting edges by drawing the sill thereagainst by means of the tap bolts 13, as shown.

It is preferable to secure the vertical meeting edges of the panels 1 to each other and to cover the same as well as the intermediate stiffeners of the panels by sheet metal pilasters on each side of the panels 1 which are cut to fit between the,v

sills and sill covers. edge connection and cover is shown in section in Figures 3 and 4. In Figure 3 angle irons 23 are shown arranged along each edge of each panel 1 with one flange extending along the side of the,

panel opposite the reinforcing flange 3 and coextensive therewith with the other flange extending at right angles thereto and terminated in line with the top of the channel 2, and may be continuous or in sections forming separated clips.

Each of the channels 2 are provided with a cover 24 of sheet metal of any preferred shape. Each cover includes along one vertical edge a face in contact and coextensive with the adjacent flanges of the angle irons or clips 23, and to which it may be spot welded, if desired, and the other vertical edge a face contacting the surface of the panel 1 and provided with a shouldered portion 25 passing over and contacting the flange 3. The two covers 24 form a pilaster on one surface of this.

A preferred form of vertical 24 in place are brought together and the cover 26 placed on the opposite side thereof in alignment with screw-threaded apertures in the cover 26, flange of angle 23, flange 3 and shouldered portions 25, or such apertures are tapped upon the job, and the bolts 28 screwed in place, thereby firmly securing the meeting edges of the panels 1 to each other and concealing the reinforced edges of the securing means by the covers 24 and 26 which form vertical pilasters on the opposite surfaces of the fireproof partition or wall. The intermediate vertical channel reinforcement member 6 is likewise covered with a similar pilaster on each side of the partition. In this case, the cover 24 is similar in outline to the exterior of the joined covers 24 and the shouldered portions 25 passes over the flange 7 of the channel 6. The cover 26 is the same as above described and the tap bolts 28 secure the two covering pilasters to each other and to the reinforcing members as above described. A modified form of the cover 26 forming the pilaster on the side 'comminuted fireproofing material.

for the inturned portions 27 of the covering pilaster 26 In this type the heads of the bolts 28 are entirely covered. After the meeting'edges have been secured this covering pilaster 26 is stiffened in place and held by the members 23 In the type of fireproof partitions or wall just described, it is preferable to fill the spaces within the sills, cornices and pilasters with powdered or The space between the intermediate stiffening members 6 and the panel may be employed for concealing the electric wiring employed for bells and lights. In buildings where the floors and ceilings are parallel to each other the panels are cut at the factory proper lengths to fit snugly between the upper and lower sills and in the case of ships where the decks have a slight curvature the panels are cut shorter and the irregularities of the ends due to the curvature will be covered by the sills, which curvature must be necessarily imparted to the sills at the factory to engage the decks.

This invention also contemplates the employment of fireproof doors wherever required in the above described fireproof partition or wall. The door frame or trim is preferably formed of sheet metal sides and top particularly shaped to be attached to the fireproof panels, as illustrated in Figures 1, 8 and 9. Figure 1 shows the top 29 of the trim curved with a grill or ventilator 30 above the door, while Figure 8 shows the top of the trim 31 flush with the top of the door 32. In any event, the tops 29 and 31 are of the same construction as the side members 33 and are secured to the panel above them in the same manner.

The side members 33 of the door trim are preferably of sheet metal formed in the shape shown in cross section in Figure 9 so as to provide a fiat surface 34 with a continuous inturned edge portion 35 adapted to contact one surface of the adjacent panel throughout and maintain the flat surface 34 perpendicular thereto; an inwardly projecting door engaging portion 36; a flat door embracing portion 37; and then preferably bent back upon itself in the form of a channel having a flange 38 parallel with the surface 35 on the opposite side of the panel 1 spaced apart therefrom and terminating in the plane of the perpendicular portions'34. In this case the stiffening channel 2 is set back a slightly greater distance from the vertical edge than in the normal joint between panels to allow for a door trim channel 39 having its langes extending towards the center of the panel with one in contact with the panel throughout from its vertical edge. It is preferable to strengthen this channel 39 by inserting an inverted channel 40 therein with the contacting flanges of both channels spot welded, if desired. Either a continuous angle iron 41 or plurality of spaced apart similar angle iron clips are provided having one flange adapted to embrace the edge of the panel 1 and the other preferably spot welded to the ends of the channel 39 on the opposite sides. The edge of the panel 1 is preferably recessed to receive the embracing flange, so that its outer surface will be flush with the panel surface. The side member 33 is so formed that with the fiat surface 35 contacting the adjacent surface of the angle iron 41, the opposite surface 38 will contact the outer flange of the edge channel 39. The side member is then secured to the edge of the panel 1 by passing a screw-threaded tap bolt through screw-threaded apertures provided at the factory or on the job,

therefor in the surface 38; the flanges of the channels 39 and 40; the panel 1; the flange of the angle iron or clip 41 and the other flat surface 35 of the member. The heads 43 of the tap bolts 42 are preferably covered by a sheet metal cover 44 preferably of similar shape to the corresponding parts of the member 33 on the other side of the panel 1, coextensive therewith and spot welded or otherwise secured to the contacting portions of the member 33. The embraced edge -by tap bolts 28, in the same manner as described in the normal vertical panel edge joint.

The top members 29 and 31 are curved or straight continuations of the side members 33 of the door trim and are secured to the bottom of a panel 1 of the proper dimensions for the purpose desired. The meeting edges of the panels 1 and 1 are secured and covered above the trim as in the normal joint described.

The sill at the bottom of the door is cut out, as shown in Figure 8, by cutting off" the longer and shorter sides 8 and 9 in line with the top of the chair 10. A spacer, preferably in the form of a channel 46, to compensate for the additional width between the side member is inserted between the leg 11 and the base 18 and the whole construction including the opposite bases 18 are embraced by the down turned edges 47 of a sheet metal door sill plate 48 preferably secured to the chair 10 by a plurality of countersunk screws 50.

The form above described is contemplated for use where sound insulation is not essential and as it employs a single sheet of fireproofing material it may be termed a solid partition in distinction from the form illustrated in Figures 10 to 14 inclusive which disclose an application of this invention to provide what may be termed a hollow partition where it is desired to insulate the partition against the transmission of sound. This form of this invention includes spacing apart from one side of the fireproofing panel 1, as heretofore described, a sheet of light fireproofing or insulating material the exterior of which may be covered by a light trowelled coat of plastic fireproofing material or, if the weight permits, a light metal plate.

Figures 11 and 12 illustrate a preferred manner in forming the hollow sound insulating partition in which a sheet 51 of fiber sound insulating material, such as celotex, is spaced apartfrom the pressed fireproofing panel 1 at the top and bottom by spacer blocks 52 and adjacent each vertical edge by similar blocks or strips. Vertical reinforcing channels 53 embrace the edge of the insulating sheet 51 and spacing strip 52. The hollow partitions are preferably held in position in the same manner as the solid partition with the bottom of both panel 1 and sheet 51 resting upon the channel 14 with the top of the sheet 51 cut to fit under the cover 15 at the top, as shown in Figure 11. The vertical meeting edges of the panel 1 and sheet 51 are preferably joined and the joints covered by pilaster, as

shown-in Figure 12, in which pilasters'similar to covering pilasters 26, illustrated in Figure 4, are employed on' each side-of this joint in which the tap bolts 28 engage the flanges of the channels 53 resting upon the inner side of the panel 1 and preferably the adjacent spacing strip 52 while the tap bolts 28 pass through the opposite flange, the sound insulating sheet and preferably engage the opposite side of the spacing strip 52. If desired, stiles, rails and moulding may be applied as for securing, covering and decorating means, as shown in Figure 10. The top and bottom mouldings 54 preferably extend beyond the bases 18 and cornices 19 and the exteriors of the upper and lower sill portions 8 and 15 to which they may be tapped, spot welded or otherwise secured.

In this hollow partition the door frame is preferably of the same type as described in Figure 9, the reinforcing channel 53, spacer strip 52 and insulating sheet 51 being substituted for the reinforcing channel 2 of Figure 9. The spacer strip 52 and sheet 51 in passing over the top of the door frame rest upon the channel 40, as shown in Figure 13. The door sill is of the same construction as shown in Figure 8.

The doors illustrated in both types of partitions are of the flush door type and necessarily must be fireproofed to complete the fireproof partition and such a door is contemplated as shown in Figures 8, 9, 13, 14, 15 and 16. One form contemplates constructing one face of the door from a single sheet 54 of thin metal bent at right angles at the edges, said edges continued to form a portion 55 of the desired thickness of the door and then extended into depending flanges 56, with the corners of the portions 55 and the flanges 56 welded, as shown in Figures 8, 9 and 16. In this type it is preferable to secure a panel 1 of fireproofing material such as used in the panels 1 of the partition between two sheets 51 of insulating material similar to the sheets 51 of the partition between the metal sheet 54 and the flanges 56. The portion 55 is depressed at the proper places to receive and allow the hinges to be secured thereto and provision is made on the opposite side for a rim lock 57.

Transverse reinforcing channels 58 with oppositely extending flanges 59 are preferably provided on each'side of the rim lock 57 which flanges embrace the filling layers 51, 1 and 51 and the space between the channels 58, rim lock 57 and opposite end of the space filled by a block of insulating material. The webs 60 between the flanges are extended therebeyond at each end of the channels 58 and bent at right angles thereto to engage the portions 55 and are preferably spot welded thereto. Other transverse reinforcements of the same type, preferably with the backs of the channel webs against each other, may be employed, as shown in Figure 15, wherever desired.

Another form contemplated is shown in section in Figures 13 and 14 in which the frame or outer edge of the door is formed of a continuous channel 61 having depending flanges 61 which are adapted to engage and hold between them a fireproofing panel 1 and a sheet of insulating material 51 separated by spacing blocks or strips 52. This may be provided with transverse reinforcing channels 58 where desired and for providing space for the rim lock 57 as heretofore described.

The surfaces of both types of doors formed by the sheets 51 may be covered by a light trowelled coat of plastic fireproofing material or, if the weight permits, by a light metal plate.

What I claim is:

1. A panel for fireproof partitions, comprising a sheet of flexible compressed flreproofing material cut to fit, channel irons arranged on the same side and adjacent the longest edges of the panel with a flange resting against the panel surface, said flange extended at each end and bent over to embrace the transverse edges of the panel, the edge of the embraced portion of the panel cut to receive the embracing flange, and means passing through the panel and opposite embracing flange members to engage said members to said panels.

2. A panel for fireproof partitions, comprising a flexible fireproof material cut to fit, channel irons arranged on the same side of the panel with a flange resting against the panel surface and an intermediate parallel channel iron on the same side having its flanges bent at an angle so that said flanges both rest upon the panel surface, the flanges of said channels resting against the panel surface provided with a plurality of struck out tongues passing through the body of the panel and bent to engage the opposite surface to hold the flanges in close contact with the panel, the ends of said flanges extending beyond and bent over the transverse edges of the panel, and means passing through the embracing portion of the flanges and embraced portion of the panel to secure the same firmly together and to impart rigidity to the said panel.

3. A fireproof partition including a plurality of panels of fireproof material, each panel provided with a plurality of metal stiffening members, secured thereto in parallel relation to its vertical edges, and a covering for each stiffening member including a metal cover passing over said member having a portion bent back to rest upon the surface of the panel and overlap a portion of the stiffening member, with a correspondingly located cover on the opposite side of the panel having a flat portion resting upon that surface of the panel, and securing means passing through said latter cover, the body of the panel, the stiffening member on the opposite side and the overlapping portion of the first cover to unite the said parts and cover said stiffening member.

4. A fireproof partition including a plurality of panels of fireproof material, each panel provided with a metal stiffening member secured thereto adjacent each vertical edge, and means for covering the respective stiffening members and securing the contiguous panels to each other including a separate metal cover passing over each respective stiffening member with a portion bent to rest upon the surface of the panel and overlap a portion of the respective stiffening member, another portion of each cover bent to pass about the edge of the panel supporting it to engage the opposite side thereof coextensively with the respective stiffening member, with a correspondingly located cover and securing means on the opposite side extending over the meeting edges of the contiguous panels coextensively with the stiffening member covers, and securing means passing through the latter cover, the portion of the first cover embracing that side of the panel, the body of the panel, the stiffening member and the overlapping portion of the first cover on the other side of the panel, as arranged on each side of the meeting edges of the contiguous panels, to cover the stiffening members and embracing cover portions and at the same time secure the contiguous panels to each other.
